Aeagle Spindle Assembly 42" Deck Replacement 2-Pack for Cub Cadet MTD XT1 LT42 XT2 LX42 — OEM Fit, 6-Point Blade Mount

High‑strength 42" spindle assemblies (2-pack) that replace Cub Cadet/MTD part numbers 618-06976, 618-06976A, 918-06976 and 918-06976A to restore mower deck performance.

If your Cub Cadet or MTD lawn tractor is running a 42‑inch deck and showing signs of uneven cutting, excess vibration, or worn blade mounting, these Aeagle spindle assemblies are built to match OEM fit and dimensions. Each kit includes two fully machined spindles and two pulleys sized to the original specifications so you can swap assemblies without modifying the deck. The assemblies are engineered for a 6‑point star blade mount and are compatible with many XT1, XT2, LT, LX and CYT series tractors that use the listed part numbers.

Which mower models will these spindles fit?

These spindles are designed to fit a range of Cub Cadet and MTD 42" deck machines that originally used parts 618‑06976 or 918‑06976 (and their A revisions). They conform to the factory pulley diameter and mounting pattern so installation is direct on compatible decks. Always compare your deck's mounting holes and pulley size to confirm fit before purchasing.

• Fits Cub Cadet XT1‑LT42, XT1‑LT42 C, XT2‑LX42 KH, XT2‑LX42 KW, LT42, LT42C, LX42
• Fits MTD CYT4220 and CYT4220SE models with 42" deck
• Direct replacement for part numbers 618‑06976, 618‑06976A, 918‑06976, 918‑06976A
• Match mounting bolt pattern and 6‑point star blade mount

How do these spindles restore cutting performance?

Worn or damaged spindles cause wobbling blades, scalloped grass, and premature belt wear. Replacing both spindles in a compromised area evens blade height and reduces vibration so you get a more consistent cut. These assemblies include pulleys sized to the original 5‑1/2" OD to retain proper belt tension and routing.

• Pulleys matched to OEM 5‑1/2" outside diameter
• Spindle height approximately 6‑3/16" for correct blade clearance
• 6‑point star blade mount for secure blade retention
• Sold as a two‑spindle kit to help balance deck repair

What should I check before installation?

Before replacing spindles, confirm the deck model, measure the pulley diameter, and inspect blade mounting for the 6‑point star pattern. Also check deck spindle bolt sizes and spindle shaft length to ensure the new unit aligns with existing hardware. If belts or blades are worn, replace them together for best results.

• Verify your tractor model and deck size (42")
• Measure pulley OD and compare to 5‑1/2" spec
• Confirm blade mount uses a 6‑point star pattern
• Inspect belts and blades; replace if worn

Is this a complete drop‑in replacement or do I need extra parts?

The Aeagle kit contains two spindles plus two pulleys and is intended to be a near drop‑in replacement for the listed part numbers. In many cases you can reuse the existing mounting bolts and hardware, but rounded or corroded fasteners should be replaced. Bearings and seals are preinstalled; however, if your deck has unique accessories you may need model‑specific fasteners.

• Kit includes 2 spindles and 2 pulleys for immediate replacement
• Bearings and seals preinstalled for convenience
• Reuse OEM bolts if in good condition; replace corroded hardware
• Check belt alignment after installation

Who is this for: This two‑pack Aeagle spindle assembly is aimed at homeowners, landscapers, and repair technicians maintaining Cub Cadet or MTD tractors with 42" decks that require direct replacements for part numbers 618‑06976/918‑06976. Choose this kit if you need OEM‑dimension spindles with matched pulleys to eliminate blade vibration and restore even cutting across the mower deck.
